JavaScript concurrency with Atomics

JavaScript’s concurrency game just leveled up with Atomics.waitAsync() from ECMAScript 2024. Imagine pausing one thread while the rest of the app keeps humming—no freezes, no bottlenecks. It’s async, non-blocking, and lets you synchronize threads like a wizard.

Here’s how I set it up: a shared buffer acts as a notepad for threads to pass messages. One worker waits, but thanks to Atomics.waitAsync(), the main thread stays free to handle other tasks. Then, when a second worker signals, the first one jumps back in.

const sharedBuffer = new SharedArrayBuffer(4);
const int32 = new Int32Array(sharedBuffer);

Atomics.store(int32, 0, 0);

Atomics.waitAsync(int32, 0, 0).then(() => {
    console.log("Worker resumed after signal");
});

// Meanwhile, in another worker
Atomics.store(int32, 0, 1);
Atomics.notify(int32, 0, 1);

This async wizardry finally lets JavaScript tackle multi-threaded tasks without bogging down the UI. Ready to power up your app? For the full details, check out the full article.
